HARNESS-LOOP MACHINE.

SPECIFICATION forming part of Letters Patent No. 299,406, dated May 27, 1884.

' Application filed May 29, 1882. (Model.)

T at whom it may concern.-

Be it known that I, PETER LANDFRIT, of Cincinnati, Hamilton county, State of Ohio, have invented certain new and useful Improvements in Machines for Finishing Harness- Loops, of which the following is a specification.

My invention relates to the mechanism for finishing the various-sized loops on harness, and has reference in general, first, to the formation of the dies whereby the various loops are finished, and, secondly, to a peculiar form of clamp for holding said dies. By the means now employed it is a difficult matter to finish the harness-loops, and especially those on the bridle-blinds and on straps of greater width than the loop, in such a manner as to give them a symmetrical appearance; and the object of my invention is to overcome these difficulties.

Referring to the drawings forming part of this specification, Figure 1 is a top view of the clamp for holding the various dies. Fig. 2 is a side or edge View of the same, showing a harness-loop clamped therein. Fig. 3 represents one of the harness-loops as finished. Fig. 4 is an edge view of the clamp with the dies shown in position thereon. Fig. 5 represents in perspective the dies for forming short loops, the same dies being shown in Fig. 4 in position on the clamp. Fig. 6 is a top view of the clamp having attached thereto the dies or jaws to be used for forming the loop on a bridle-blind. Fig. 7 is an edge view of Fig. 6. Figs. Sand 9 represent the jaws shown in Figs. 6 and 7 detached from the extensions a, in each of which is formed a longitudinal slot, a, through which slots pass bolts 12, which latter are secured to the body A, and upon which are thumb-nuts b,washers d and space w.

b being interposed between the thumbnuts and the face of the arms'a, the washers being wide enough to rest on the arms at each side of the slot a, so that when the thumb-nuts are screwed down tightly upon the washers the arms a will be tightly clamped, and by this construction the jaw A may be moved toward or away from the stationary jaw A and secured firmly in the desired position. This adjustable jaw is moved back and forth by any suitable means, preferably by a screw,B,which passes through a raised nut, B, connected to or forming a part of the body A, one end of said screw being secured to the jaw A in such a manner as to be permitted to turn therein and yet be secured thereto, so that as the screw B is turned in the nut B the jaw A may be moved in the desired direction. The free end of this screw B is provided with a crank or hand wheel, 0, by means of which it is turned. The side of the sliding jaw A is provided with lugs or feet D, which rest and slide upon the upper surface of the body A, and keep the jaw raised a space, w, above the body;and at the lower edge of the stationary jaw A is the channel d, extending the entire length of the j aw,and equal in width to thedistance at which the sliding jaw is held above the body A. If, now, it is desired to use the clamp for finishing loops on a straight strap, as represented by Fig. 3, the jaws above described are sufficient for the purpose. A stick'or core, E, of the desired width and thickness, is slipped into the loop, and the latter is then placed upon the body A against the stationary jaw A, the channel cl permitting the side of the loop to rest closely against the said j aw; Should the strap to which the loop is attached be, as is frequently the case, somewhat wider than the loop itself, that part of the edges of said strap which project beyond the sides of the loop will be respectively received into the channel The sliding jaw A is now moved up by means of the screw B until it rests closely and firmly against the opposite side of the loop. A die, E, having a plain face, or one designed to form an appropriate figure on the face of the loop, is now placed between the jaws A and A the face of the die resting upon the loop, and this die is then pressed by any appropriate mechanism firmly j aw A down upon the loop, which, being firmly held between the jaws A and A, is thus caused to assume a symmetrical shape.

A very convenient form of press to be used in connection with my invention is the ordinary bcnch-vise found in all shops, as my invcntion may readily be placed in such a vise, and in small shops which have no other presses this will be found to be of great advantage.

In finishing short loops I preferably employ the supplemental jaws, F 1 shown in Fig. 5. The jaw F is connected to a base plate, r, and a channel, (1, similar in formation and purposeto the channel (I at the lower edge of the stationary jaw A, is formed in the an gle between the jaw F and the baseplate c. This base-plate c is placed on the upper face of the body A, the back of the jaw F resting against the face of the stationary jaw A, occopying the position shown in Fig. 4, in which position the jaw F serves the purpose of the stationary jaw. The jaw F is provided with a flange, f, which hooks over the upper edge of the sliding jaw A. The fiangef preferably has a notch, 1", which, when the jaw F is to be used, engages with a lug, c, on the upper edge of the sliding jaw A, thus preventing thejaw F from slipping longitudinally on the jaw A"'. When. these supplemental jaws are employed, the finishing of the loop is effected in a manner similar to that before described.

While I have thus fully described the jaws F h", I do not make any claim for them in this application, as I purpose making them the subject of separate Letters Patent.

It has heretofore been a difficult matter to procure a perfect and symmetrical finish on the long loop which is attached to one edge of the bridle-blinds, owing to the dilficulty in bringing any pressure to bear against the sides of the loop, in consequence of its position with relation to the blind; but I accomplish this in a perfect manner by the use, in connection with the clamp, of the supplemental jaws shown in Figs. 6 to 9, which jaws, when they are to be used, are suitably connected to the jaws A A, a very convenient mode of so connecting these supplementary jaws being that shown in the drawings.

The jaw G, consisting of a base, and a face, is attached to the stationary jaw A. This jaw G is provided with feet G, which rest on the body A of the clamp and elevate the base g, upon which the loop is to rest, and on the back of the face 9 are the dovetailed flanges or lugs h, which latter are usually placed (when the jaw Jr is to be employed) at each end, respectively, of the stationary jaw A, the ends 7 of which, or equivalent projection on saidjaw, are dovetailed, as shown in Fig. 6, so as to fit snugly between the lugs 71. Another jaw, J, is connected to the sliding This jaw J consists of a body, j, and a head or face, 7:, the head being connected to the body by the arches 7:, so formed as to raise the face 7; up to a level with the face of the jaw G. This jaw J' is retained in position on the sliding jaw A by means of dovetailed flanges m on the back of the body j, which flanges engage with the projections formed on, and preferably identical with, the ends of the slidingj aw, which are dovetailed to correspond with the formation of said flanges. Between the bodyj and the head 7a of the die 3' is an opening, ll, through which the blind is to be placed; and when it is placed in this position and the sliding jaw moved up until the loop is clamped between the jaws G and J, the parts occupy the position shown in Fig. 7. By the use of these supplemental jaws, (r and J, in connection with the clamp, I am onabled to finish the loop on the blind in a manner similar to that described for finishing a loop on a straight strap, and with an equal degree of perfection.

By the employment of the clamp and the jaws above described it will be seen that any of the loops upon a harness may be perfectly shaped.

If it is desired to stamp any particular design on the sides of the loops, the faces of the jaws may be formed accordingly.

Having thus described my invention, what I claim as new and of my invention, and desire to secure by Letters Patent, is as follows:

1. The base or frame A, having jaw A, provided with projections 3 and sliding jaw A having projections X, adapted to receive in terchangeable jaws or dies, in combination with arms a, having slots to, and nutsb, and.
